DISPENSING MEANS FOR BEVERAGES CONTAINING CHOCOLATE, COCOA, ETC.

Application filed November 4, 1921. Serial No. 512,719.

To all whom it may concern:

Be it known that I, HARR C. LYONS, a citizen of the United States, and a resident of the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Dispensing Means for Beverages Containing Chocolate, Cocoa, llto, of which the following is a specification.

improvements agniertain to the type of dispensing apparatus set forth in Letters Patent No 1,367,823,issued to me Feb. 8, 192i, and relate more particularly to the arrangement and construction of the dis- :Pensing faucet used in conjunction with the drain duct which is a distinctive feature of my fluid dispensers 'enerally, as exemplified first in Letters Patent No. 1,181,783, issued to me May 2, 1916, and in subsequent patents for milk and pensing apparatus.

is set forth mole particularly in the aforesaid Letters Patent No. 1,367,823, in the preparation of beverages containing chocolat-e, cocoa and the like the extract of cocoa is diluted more or less with hot milk and water, and is only partially dissolved there by, the admixture being a solution in which the heavier constituents settle to the bottom thereof and constitute a sediment of viscid, scmi-fluid character. while the upper part of the concoction is relatively thin and fluent. Hence, in dispensing beverages of this character, it was formerly necessary to stir and agitate the admixture preparatory to pouring, or to prepare the same in small quantities for immediate use,disadvantages which I obviate by my method of utilizing the flow of the more fluid constituents as a vehicle to flush out the heavier constituents of the admixture substantially as set forth in said Letters Patent N 0. 1,367,823.

My present improvements are designed to overcome certain objections incidental to t in form of dispensingxfaucet shown therein, in which the chocolate receiving compartment thereof is continuously in communication with the heavier semi-fluid constituents, so that on the flushing out of said pocket by the lighter liquid vehicle the latter is apt to draw off more than the prescribed or desired quantity of chocolate syrup, so called. in other words. the faucet shown and de scribed in said Letters Patent is not a measuring faucet in the strict sense of the word, and does not accurately prescribe the quancream distity of c-hocolate-satiu'atcd syrup discharged when the valve 1i lug is turned to open communication with the channel through which the lighter liquid contents of the urn pass t c-discharge spout. Furthermore, under certain conditions, clogging of the faucet is apt to occur by reason of said continuous communication between the receiving pocket in the faucet and the area of concentrated chocolate solution, especially when the latter is surcharged and pasty in character.

These difliculties I obviate by my present invention, which consists essentially in the specific construction, combination, and arrangement of parts and appurtenances heredescribed and claimed,-a distinctive feature being the provision of a rotatable valve plug formed with a measuring compartment which is cut off from the chocolate-syrup supply when the faucet is used for dispens ing purposes, while at the same time communication is established with the floatable drain duct, whereby the fluid contents of the upper portion of the urn is utilized to effect the washing out and discharge of said chocolate syrup measuring chamber, as hereinafter more fully set forth.

C, represents an urn or container of any desired or suitable construction and external configuration, designed for the reception and storage, temporarily, or the constituents of the .cacao beverage to be. dispensed throughthe faucet D. The rear portion of the floor 0, of the reservoir is preferably -convergently inclined toward said dispensing .faucet D, as shown particularly in Fig. 1,.0'fthe drawings, for the purpose of concentrating the sedimentary constituents ot the concoction in suitable juxtaposition to .the outlet .0, which communicates with the inlet (Z,in the upper side of the casing (Z, in which latter the valve plug p, is mounted, said-casing being attached rigidly and permanentlyto the underside of the urn C,

The valve plug 2), is slightly conical, tapering rearward, and is held-to its concavoconoidal seat in the casing cl, by a spring s, interposed between its vr'orward extremity and a cap L", screwing .onto the outer end ofthe valve casing d, as Sl10W 11-RIOLB'PQITClCLI Near its ttoi'ward with the course provided with the usual stem 7 and handle pa t0 facilitate manipulation, a half turn of said plug in either direction su'llicing to open or close the faucet as the case may be.

()nthe same side ofthe valve plug 39, as

the inlet port p, is the discharge port 39 which, when the plug is reversed or turned into position fordischarge, coincides with the spout (Z of the casing cl", asshown in Fig. 7. Vflhen the valve plug-p, is in this *POSiUOD its vent port jf COlllClClGS with the vent hole (Zfl'in the upper-side oft-he casing (W -so as tOizlCllltfltB the discharge of the a e. contents olthe measuring chamber p Likewise. when the valve elu is thus reversed'i-roni normal position, its rear inlet port 77, coincides with the fluid vehicle inlet port (F, in the casing (Z, as also shown 111'S2L1Cl Fi 7. said inlet )ort 2 being on the side :3 7 of tne valve plug opposite to that on which 'the inlet port p, and discharge port- ;0 are situated.

The vehicle inlet port 2?, acts in part as a socket for the discharge duct 6', forming the lower extension of the hollow trunnion e, on which the knuckle sleeve 7", of the fioatable drain tube f, is mounted as heretofore in my float-drain type of liquid dispensers,the

lower end. of said fioa-table drain tube f, communicating through a port 0 with the inter ior oi? the hollow trunnion e, as shown in Fig. 3, and the sleeve f, being held on the trunnion e, by a cap screw f The float f, is attached to the upper end olf-the drain tube as heretofore. The inlet 0 is of shape and area suificient to maintain com munication with the lower-end of the float able duct. 7', irrespective otthe liquid level within the reservoir C; and the float f niaintainsthe mouth of the said drain tube 7, a suificient distance below the liquid level to. insure a flow of liquiduponoccasion, while avoiding-contact with the skin or scum that is apt to collect and float on the top thereof. I

Thus, upon turningthe valve plug 29, into the position shown in Fig. 7, a flow of relatively .thin vehicle liquid will be induced through the drain ductf, trunnion e, duct 6,

and inlet port p, into and through the-measuringchamber p, which thus becomes also essentially a mixing chamber, in that the diluted milk (which'ordinarily forms the flushing vehicle) mingles with and takes up a the impalpahle cocao ingredient,- diluting the impregnated solution thereof, and insuring its discharge through the nozzle (Z It will-be seen thatby this construction and arrangement otparts only aprescribed quantity o'fcocao syrup can'be discharged at each dispensing operation, although more or less milk may he '121(l.(l8(l thereto and passed through the aneasuring chamber p, into a receptacle held below thespout diaccording to preference or requirements.

What I claimasmyinvention and desire to secure lay-Letters Patent is,

In liquid dispensing apparatus of the character designated, the combination of a container having a discharge duct, a'dispensing iiaueet' connected therewith and formed with a rotatable valve plug. having a measuring chamber with a discharge port and with an inlet on one and the same side. the discharge port being comniunicatable with a discharge port of the containermand on the other side with an inlet coinniunicatsn ble with said discharge duct. and a ioatable drain duct cou'iinunicatable with said discharge duct and provided with bi'ioyaiit means for maintaining its inlet port below the liquidlevel in :the container, for the purpose described.
